Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a composition, in particular a crop protection agent, a plant regeneration agent and / or plant growth agent, for use on plants, in particular as a concentrate, casting or spraying. The invention also relates to a preparation process of the composition and to a use of the composition by impregnation or spraying of plants, for growth promotion, for regeneration and / or for protection against diseases.

BACKGROUND OF THE INVENTION

Plants are exposed to a variety of different and changing environmental influences, such. Cold weather, hot weather periods, drought, wetness, pollutants in air and soil, germs, etc. In order to mitigate or avoid the negative consequences of such influences, plant nutrients are often used. Plant growth and regeneration agents are widely available. Various compositions act differently fast, different degrees and different lengths and are used accordingly. When plants are affected by sudden environmental changes, the reaction of the plants is often very violent; e.g. a plant may die due to a brief but severe cold snap. Common fertilizers often do not help in such extreme situations, as they are e.g. can not be absorbed fast enough by the plant.

It is therefore an object of the present invention to provide a fast-acting composition which is conducive to the growth and regeneration of plants. That It is intended to provide a plant protection agent, in particular a plant growth agent or plant regeneration agent, which does not have the disadvantages of the prior art or at least partially avoids it. Furthermore, it is an object to provide a composition which reduces adverse consequences of adverse environmental conditions, such as frost and acid rain, and various diseases. It is also an object to provide a composition which promotes the growth of plants and / or the regeneration after harmful environmental impact. The effect should unfold in flower-bearing plants as well as in green plants. In particular, the active compositions should consist of substances which are harmless especially for humans and animals. In addition, the active ingredient should be provided as a liquid.

DESCRIPTION

The above objects are achieved according to the invention by a growth-promoting and regeneration-promoting composition for use on plants, in particular as a concentrate, casting or spraying agent, wherein the composition is characterized in that this at least one alkali salt and / or an alkaline earth metal salt, a vitamin E. Compound, a solvent and optionally water. This composition helps with strong-acting and / or sudden harmful environmental influences in a short time. Treated plants recover quickly. The composition is environmentally friendly and leaves no harmful residues on plants and in the soil.

A concentrate can not contain water or a certain amount of water. A concentrate is characterized in particular by the fact that further addition of water provides an optimum concentration for spraying or watering plants.

Additional advantages and objects of the present invention will become apparent from the following description.

Preferably, the vitamin E compound consists of at least one tocopherol, α-tocopherol in many cases shows the best effect.

More preferably, selected from the group of alkali and / or alkaline earth metal salts at least one alkaline earth metal salt, wherein the selection advantageously includes at least one magnesium salt.

Conveniently, the magnesium salt consists of magnesium chloride (MgCl2) This can be added, for example, as MgCl2 · 6 H2O and / or MgCl2 · 4 H2O.

The solvent, which is different from water, is mainly used to bring the vitamin E compound in solution. A selected solvent should therefore have a much higher solubility for said vitamin E compounds than water. Advantageously, at least one alcohol is used as the solvent, conveniently this is ethanol or another harmless and tolerable solvent for the plant and its environment. The term solvent is to be understood in the context of the present description, a different solvent than water.

Preferably, the weight ratio of alkali or alkaline earth metal salt compound to vitamin E compound is at least 10,000 to 1 and optionally at most 500,000 to 1, more preferably the weight ratio of alkali and / or alkaline earth metal salt compound to vitamin E compound in the range of 20,000 to 1 to 320,000 to 1.

In an advantageous embodiment of the invention, the composition is characterized in that it forms an aqueous solution containing at least the following ingredients: an alkali metal or, preferably, an alkaline earth metal salt compound, in particular magnesium chloride, preferably in an amount of at least 40 g / l, more preferably at least 60 g / l, more preferably about 80 g / l, a tocopherol, in particular α-tocopherol, preferably in an amount of at least 0.05 mg / l, more preferably at least 0.75 mg / l, more preferably at least 1 mg / l and more preferably in the range from 1 mg / l to 3 mg / l and a solvent, especially an alcohol, e.g. Ethanol, preferably in an amount of at least 5 ml / l, more preferably of at least 10 ml / l, more preferably of at least 25 ml / l, more preferably at least 40 ml / l, more preferably about 50 ml / l.

The inventive composition can be provided with the following production method: the vitamin E compound is dissolved in the solvent and the resulting solution is mixed with the alkali or alkaline earth metal salt and optionally the water.

Conveniently, e.g. the alkali or alkaline earth metal salt are dissolved in the water. The solution of the alkali or alkaline earth salt and the solution formed from solvent and vitamin E compound can then be mixed together.

The inventive composition is suitable for soaking or spraying plants. In particular potted plants can be treated advantageously with this composition.

Expediently, an aqueous solution of the composition according to the invention is used, which is formed on dilution in the casting water or which is diluted to a desired or advantageous concentration by adding to the casting water. It may be expedient to set the desired dilution directly during the production process, in order then to be able to quickly or simply spray or spray plants with this prepared dilution as needed.

Advantageously, the composition of the invention is used at a vitamin E compound content of at least 0.5 mg / L (i.e., milligrams per liter of aqueous solution), preferably at least 1 mg / L, and more preferably about 1 mg / L. Good results are also achieved in quantities up to 4 mg / l. The best effect is achievable in many plants with tocopherol, in particular α-tocopherol. Alpha-tocopherol is particularly advantageously used in the range of 0.5 mg to 5 mg per liter of aqueous solution, and more preferably from 1 mg to 3 mg per liter of aqueous solution.

Advantageously, the composition according to the invention is used at a content of the alkali or alkaline earth salts of at least 40 g / l (i.e. grams per liter of the aqueous solution), preferably of at least 60 g / l and more preferably of approximately 80 g / l.

Conveniently, the composition according to the invention is used with the lowest possible content of solvents. A content of the solvent of at least 5 ml / l (ie milliliters per liter of the aqueous solution), preferably of at least 10 ml / l, more preferably of at least 25 ml / l and more preferably of approximately 50 ml / l, has proved to be advantageous , In order not to damage the plants, it is recommended not to exceed a maximum content of 100 ml of solvent per liter of aqueous solution. This limit is desirable especially for ethanol as a solvent.

Preferably, from 5 to 100 ml of solvent, with ethanol being the preferred solvent, is used to dissolve from 0.5 mg to 5 mg of a vitamin E compound, e.g. α-tocopherol, used. The solution is then mixed with water and optionally the alkali or alkaline earth salt.

A particularly fast and efficient effect is achieved by spraying the leaves of the plant (so-called foliar application). The intake via the leaves can be limited. Thus, under certain circumstances, it may be advantageous to soak with the aqueous solution according to the invention during prolonged treatment of a plant, as a result of which a steady uptake via the roots can take place.

At least in representatives of the following plant families, a beneficial effect could be observed by applying the inventive composition: nightshade family (such as tomatoes and peppers), cucurbits (such as melons and cucumbers), daisy family (garden lettuce such as iceberg lettuce) and labiates (as eg rosemary). It has been observed that the treatment of the plants is generally more robust to external influences and also less susceptible to diseases, especially fungal diseases.

In principle, it is believed that the inventive composition acts on all plants insofar as photosynthetically active plant parts are obtained with the inventive composition, e.g. by spraying the said plant parts or by pouring. The reasons may be related to the fact that forms of vitamin E (which includes in particular the preferred forms of tocopherols and tocotrienols) which are generally attributed antioxidant activity, in plants can interfere with the regulation and protective mechanisms of photosynthesis.

In particular, beneficial effects are only due to the ingredients mentioned, i. of alkali salts or alkaline earth salts, vitamin E compounds, solvents and water. Additional additives can be dispensed with. In particular, can be dispensed with the addition of microorganisms.

The invention will be explained by way of examples.

EXAMPLE 1

Preparation of a composition according to the invention. Mix and dissolve 1 mg of α-tocoferol in 50 ml of ethanol. Dissolve 80 g magnesium chloride in a little water (preferably at least 150 ml). Combine alcoholic tocoferol solution and aqueous magnesium chloride solution, mix and add up to 1 liter of water.

EXAMPLE 2

Young pepper plants of the genus Capsicum, about 2 to 3 weeks old, are sprayed with the composition of Example 1. In a comparative experiment young pepper plants are sprayed with tap water.

Measurements of the height of the plants before treatment and 2 days after the treatment show that when using the inventive composition, a length growth of 4 to 5 cm and when using ordinary water, a growth in length of 0.5 to 1 cm is found.

EXAMPLE 3

Flowering rosemary plants of the species Rosmarinus Officinalis (also called Gunder or Swiss rosemary), distributed over different pots, are sprayed as follows: <tb> 1. <sep> First samples: with aqueous solution consisting of 1 mg of α-tocopherol, 50 ml of ethanol and 80 g of magnesium chloride per 1 liter (according to Example 1). <tb> 2. <sep> Second samples: with tap water.

After a short rest of about 1 hour, the plants are exposed for four hours a cold shock at -18 ° C. After removal, all plants are withered. During one week the regeneration process of the plants is observed:

The plant of the first sample, those which have been treated with a composition according to the invention, recover within two days. The plants of the second sample do not recover during this time.

If a plant of the second sample, which was initially treated with water, treated on the third day later with the inventive composition of Example 1, so this plant can still recover. If no subsequent treatment is undertaken, the plant dies within about a week.

Similar results are obtained when the plants are soaked instead of sprayed. Similar results are also obtained if the plants are treated instead of before the cold shock after the cold shock, i. sprayed or poured.

EXAMPLE 4

Rosemary plants of the species Rosmarinus Officinalis distributed to different pots are sprayed as follows: <tb> 1. <sep> First samples: with aqueous solution consisting of 1 mg of α-tocopherol, 50 ml of ethanol and 80 g of magnesium chloride per liter (according to Example 1). <tb> 2. <sep> Second samples: with aqueous solution consisting of 1 mg of α-tocopherol and 50 ml of ethanol per liter. <tb> 3. <sep> Third samples: with aqueous solution consisting of 80 g magnesium chloride per liter. <tb> 4. <sep> Fourth samples: with tap water.

After spraying the plants are allowed a rest period of a few hours. Thereafter, the plants are exposed to a cold shock at -20 ° C for 4 hours. After removal, all plants are withered. The plants will now be left in the shade for several days. Then the condition of the plants is reassessed on the fourth day after the cold shock treatment: the plants of Samples 2, 3 and 4 are still withered and now additionally have brown or brown spotted leaves. The plants of sample 1, however, have green leaves without brown discoloration. In addition, the general condition of the plants of the sample 1 is better than that of the plants of the samples 2,3 and 4.

The plant of the first sample, those which have been treated with a composition according to the invention, thus recover within four days. The plants of the third and fourth sample do not recover during this time.

Similar results are obtained when the plants are soaked instead of sprayed. Similar results are also obtained if the plants are treated instead of before the cold shock after the cold shock, i. sprayed or poured.

EXAMPLE 5

Seed of the iceberg lettuce of the genus Lactuca was impregnated after sowing with an inventive composition according to Example 1. After four days, the first sprouts showed up, while normally only after weeks are such to be expected. A control group, which was soaked with water alone, produced no sprouts in this short time.

EXAMPLE 6

Balcony tomatoes of the genus Solanum sect. Lycopersicon are first sprayed with the inventive composition of Example 1 and cooled after a rest hour for about 2 hours at 2 ° C. Subsequently, the same plants are planted in the garden in the soil and sprayed again with the composition of Example 1.

After four to five days burned spots have formed on the leaves, but after 7 days many new shoots develop. The plant is recovering amazingly fast.

Plants of a comparison group, which were cooled for about 2 hours at 2 ° C and then planted in the garden in the soil, did not recover but died from.

EXAMPLE 7

Balcony tomatoes of the genus Solanum sect. Lycopersicon are cast with the composition of Example 1. A comparison group is poured only with water. The treated plants are stored for about 6 hours at -18 ° C. Then the same plants are inserted in the garden in moist soil.

The plants which were cast with the composition according to the invention recovered after 5 days from the cold shock. The plants of the comparison group died.
